A Mixed Distribution Model of Pointing Error of Aircraft

Shanghai Jiaotong Daxue xuebao
In the space exploration mission, the aircraft will be affected by mechanical shocks, tracking noise and other factors to cause angular micro-vibration, so that the antenna pointing error is always non-zero, which will affect the communication link ...

Electron acoustic instability in four component space plasmas with observed generalized (r,q) distribution function

AIP Advances, 2019
Electron acoustic instability in magnetized four component plasma has been studied by employing non-Maxwellian generalized (r, q) distribution function.

A Test of Fit for Bivariate Distributions

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1973
Summary Tests of fit based on generalized minimum χ2 techniques are developed for bivariate distributions. The asymptotic null distribution of the test statistic is χ2 while the asymptotic non-null distribution turns out to be that of a weighted sum of independent non-central χ2 variates.

Degree distributions in recursive trees with fitnesses

Advances in Applied Probability, 2023
AbstractWe study a general model of recursive trees where vertices are equipped with independent weights and at each time-step a vertex is sampled with probability proportional to its fitness function, which is a function of its weight and degree, and connects to $\ell$ new-coming vertices. Under a certain technical assumption, applying the theory of

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Polynomial Fitting-Based Model for Tails of Radar Clutter Amplitude Distribution [PDF]

Hangkong bingqi
When high-resolution radar detected complex scenarios such as low-altitude and sea surfaces, the clutter amplitude distribution exhibited significant heavy-tailed characteristics.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Cell density–dependent nuclear‐cytoplasmic shuttling of SETDB1 integrates with Hippo signaling to regulate YAP1‐mediated transcription

FEBS Letters, EarlyView.
At low cell density, SETDB1 and YAP1 accumulate in the nucleus. As cell density increases, the Hippo pathway is gradually activated, and SETDB1 is associated with increased YAP1 phosphorylation. At high cell density, phosphorylated YAP1 is sequestered in the cytoplasm, while SETDB1 becomes polyubiquitinated and degraded by the ubiquitin–proteasome ...
